• Water flow brings debris, oil & sheen, and other pollutants from the surface

• Sediments adsorb/carry hydrophobic toxins

• From street runoff

• From leaking equipment in the vault

Where there is energized

equipment, should there also be a

pump for wastewater?

Yes!And WHY is that?

• Typical sump pumps can process spherical solids sized ½” to ¾” or smaller• About the size of a marble• Anything larger or elongated

will clog the pump

• Items that typically clog/burn up pumps• Sand• Gravel• Cleaning wipes• Trash

• No one-pump-fits-all

• Examples:• Improper power/size

• Not designed for short cycling

• Misapplied electric

Four layers of patented* Agent-Q, a unique, non-woven composite fabric structure embedded with C.I.Agent Polymers** for oil solidifications that prevents oil from reaching the pump

One layer of Agent-Q flows 400 gallons/minute/m2

Average grab strength of a nominal 60 pounds (ASTM D5034 testing) and a burst strength of a nominal 70 psi (ASTM D3786 testing)

*U.S. Patent No. 8,986,822**C.I.Agent Solidifying Polymers are listed in the EPA National Contingency Plan Product Schedule* for oil cleanup and are effective in temperatures ranging from -30°F to +130°F.
